Dr. Riccardo Corizza's phone doesn't stop ringing these days, but the callers aren't seeking his medical advice.

Corizza's phone number is the same, except for the area code, as that used by a popular sports call-in quiz show.Corizza, a Rome gynecologist, can't take his phone off the hook because he might miss emergency calls from his patients.

But he has been so overwhelmed by calls from sports fans that he has asked the state-run RAI television to change the number of the quiz show.

If that doesn't work, Corizza said he will seek a court injunction.
